Actually i want to plot the interaction and mean of a matrix by ANOVA. For example I have a matrix like below
X = rand(100,150);
there are 100 samples and 150 columns. I want to perform ANOVA and plot all interaction as well as I want to see which column is statistically significantly different from others.
Can someone help me here?

Hi,
If you want to test whether two column have same mean or not, you can check the ttest or ttest2 functions.
[h12, p12] = ttest2(X(:,1), X(:,2));
You can iterate over pairs of columns to identify which ones gives a positive true value for h_ij, or alternatively check which pairs results in low p-values.
